Copper colour and (brown) oxyde colour. All products are handmade, all produced by gifted craftsman of turkey. To prevent copper cezve/coffeepot to darken, exterior surface is polished and dip-tinning method is used for interior surface with traditional ways. It is long-lasting and enduring.
The different shaped lines on the products and other differences between them are because that they all are made by hand, every line is special to the product, they all are unique pieces. My copper products are not fabrication and they all are %100 hand made. Copper can lose its brightness depending on the circumtances of usage because of its nature. Pay attention to clean it right after using. Don't wait it dirty as it may cause it to darken.
To make them shine; swabbing with vinegared cloth may help or it can be rubbed with lemon and salt. Before using the product at first time wash it by hand with warm water and soap then wait for it to dry.
Dont ever put it in dishwasher. Don't use bleacher or wired brash. Always dry after washing it. This item is made of copper.
